Be advised, reading this post may result in lulz:
As noted in the past few posts, I'm still perfecting that oracle. I actually want to add an option to make it search the user's string and reply with a relevant (but still somewhat random) response. Anyway, I haven't gotten that far yet because of my stubbornnes. You see, I decided from the beginning that I would make the application load from one page and use document.write() to create the "answer" page.
The above worked great until I decided that I'd get ambitious and make the thing a facebook app. Setting up the JavaScript SDK wasn't hard at all, but getting that SDK to work in the document.write() html was somewhat of a challenge. No matter what I did, I couldn't get the example function provided for FB.ui to post in it. I spent hours readjusting the code placing it in all kinds of different places. I even went as far to redeclare the function fb_publish(); inside of a script within the document.write() html! Then, after that failed, I went around adding backslashes to escape everything in the function. I still don't understand why -that- failed..
As mentioned before, I was being pretty stubborn about the whole "one file" thing. The solution was a deceptively simple one: create an external .js file, include it in the document.write() html's head section. Then, you can call it from document.write(); with impunity! Cheers!
